The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8 on the AMD K7 and K8 platforms does not clear pending exceptions before proceeding to an EMMS instruction, which allows local users to cause a denial of service (task kill) or possibly gain privileges via a crafted application.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The ipx_recvmsg function in net/ipx/af_ipx.c in the     Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7268i1/4%0

  - The move_pages system call in mm/migrate.c in the Linux     kernel doesn't check the effective uid of the target     process. This enables a local attacker to learn the     memory layout of a setuid executable allowing     mitigation of ASLR.(CVE-2017-14140i1/4%0

  - Multiple array index errors in drivers/hid/hid-core.c     in the Human Interface Device (HID) subsystem in the     Linux kernel through 3.11 allow physically proximate     attackers to execute arbitrary code or cause a denial     of service (heap memory corruption) via a crafted     device that provides an invalid Report     ID.(CVE-2013-2888i1/4%0

  - It was found that if a Non-Maskable Interrupt (NMI)     occurred immediately after a SYSCALL call or before a     SYSRET call with the user RSP pointing to the NMI IST     stack, the kernel could skip that NMI.(CVE-2015-3291i1/4%0

  - The sound/core/seq_device.c in the Linux kernel, before     4.13.4, allows local users to cause a denial of service     (snd_rawmidi_dev_seq_free use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16528i1/4%0

  - net/ceph/auth_x.c in Ceph, as used in the Linux kernel     before 3.16.3, does not properly consider the     possibility of kmalloc failure, which allows remote     attackers to cause a denial of service (system crash)     or possibly have unspecified other impact via a long     unencrypted auth ticket.(CVE-2014-6417i1/4%0

  - A NULL pointer dereference flaw was found in the Linux     kernel: the NFSv4.2 migration code improperly     initialized the kernel structure. A local,     authenticated user could use this flaw to cause a panic     of the NFS client (denial of service).(CVE-2015-8746i1/4%0

  - A stack-based buffer overflow flaw was found in the     TechnoTrend/Hauppauge DEC USB device driver. A local     user with write access to the corresponding device     could use this flaw to crash the kernel or,     potentially, elevate their privileges on the     system.(CVE-2014-8884i1/4%0

  - A flaw was found in the linux kernel's implementation     of the airspy USB device driver in which a leak was     found when a subdev or SDR are plugged into the host.An     attacker can create an targeted USB device which can     emulate 64 of these devices. Then by emulating an     additional device which continuously connects and     disconnects, each connection attempt will leak memory     which can not be recovered.(CVE-2016-5400i1/4%0

  - The sound/usb/mixer.c in the Linux kernel, before     4.13.8, allows local users to cause a denial of service     (snd_usb_mixer_interrupt use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16527i1/4%0

  - The Human Interface Device (HID) subsystem in the Linux     kernel through 3.11, when CONFIG_LOGITECH_FF,     CONFIG_LOGIG940_FF, or CONFIG_LOGIWHEELS_FF is enabled,     allows physically proximate attackers to cause a denial     of service (heap-based out-of-bounds write) via a     crafted device, related to (1) drivers/hid/hid-lgff.c,     (2) drivers/hid/hid-lg3ff.c, and (3)     drivers/hid/hid-lg4ff.c.(CVE-2013-2893i1/4%0

  - It was found that reporting emulation failures to user     space could lead to either a local (CVE-2014-7842) or a     L2-i1/4zL1 (CVE-2010-5313) denial of service. In the case     of a local denial of service, an attacker must have     access to the MMIO area or be able to access an I/O     port. Please note that on certain systems, HPET is     mapped to userspace as part of vdso (vvar) and thus an     unprivileged user may generate MMIO transactions (and     enter the emulator) this way.(CVE-2014-7842i1/4%0

  - A flaw was discovered in the way the Linux kernel's TTY     subsystem handled the tty shutdown phase. A local,     unprivileged user could use this flaw to cause denial     of service on the system by holding a reference to the     ldisc lock during tty shutdown, causing a     deadlock.(CVE-2015-4170i1/4%0

  - The __ip6_append_data function in net/ipv6/ip6_output.c     in the Linux kernel through 4.11.3 is too late in     checking whether an overwrite of an skb data structure     may occur, which allows local users to cause a denial     of service (system crash) via crafted system     calls.(CVE-2017-9242i1/4%0

  - The Linux kernel built with the KVM visualization     support (CONFIG_KVM), with nested visualization(nVMX)     feature enabled (nested=1), was vulnerable to a stack     buffer overflow issue. The vulnerability could occur     while traversing guest page table entries to resolve     guest virtual address(gva). An L1 guest could use this     flaw to crash the host kernel resulting in denial of     service (DoS) or potentially execute arbitrary code on     the host to gain privileges on the     system.(CVE-2017-12188i1/4%0

  - The recalculate_apic_map function in     arch/x86/kvm/lapic.c in the KVM subsystem in the Linux     kernel through 3.12.5 allows guest OS users to cause a     denial of service (host OS crash) via a crafted ICR     write operation in x2apic mode.(CVE-2013-6376i1/4%0

  - The wanxl_ioctl function in drivers/net/wan/wanxl.c in     the Linux kernel before 3.11.7 does not properly     initialize a certain data structure, which allows local     users to obtain sensitive information from kernel     memory via an ioctl call.(CVE-2014-1445i1/4%0

  - The restore_fpu_checking function in     arch/x86/include/asm/fpu-internal.h in the Linux kernel     before 3.12.8 on the AMD K7 and K8 platforms does not     clear pending exceptions before proceeding to an EMMS     instruction, which allows local users to cause a denial     of service (task kill) or possibly gain privileges via     a crafted application.(CVE-2014-1438i1/4%0

  - A race condition was found in the way the Linux     kernel's memory subsystem handled the copy-on-write     (COW) breakage of private read-only memory mappings. An     unprivileged, local user could use this flaw to gain     write access to otherwise read-only memory mappings and     thus increase their privileges on the     system.(CVE-2016-5195i1/4%0

  - Algorithms not compatible with mcryptd could be spawned     by mcryptd with a direct crypto_alloc_tfm invocation     using a 'mcryptd(alg)' name construct. This causes     mcryptd to crash the kernel if an arbitrary 'alg' is     incompatible and not intended to be used with     mcryptd.(CVE-2016-10147i1/4%0

Updated kernel-rt packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise MRG 2.5.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system.

  * A denial of service flaw was found in the way the Linux     kernel's IPv6 implementation processed IPv6 router     advertisement (RA) packets. An attacker able to send a     large number of RA packets to a target system could     potentially use this flaw to crash the target system.
    (CVE-2014-2309, Important)

  * A flaw was found in the way the Linux kernel's netfilter     connection tracking implementation for Datagram     Congestion Control Protocol (DCCP) packets used the     skb_header_pointer() function. A remote attacker could     use this flaw to send a specially crafted DCCP packet     to crash the system or, potentially, escalate their     privileges on the system. (CVE-2014-2523, Important)

  * A flaw was found in the way the Linux kernel's CIFS     implementation handled uncached write operations with     specially crafted iovec structures. An unprivileged     local user with access to a CIFS share could use this     flaw to crash the system, leak kernel memory, or,     potentially, escalate their privileges on the system.
    (CVE-2014-0069, Moderate)

  * A flaw was found in the way the Linux kernel handled     pending Floating Pointer Unit (FPU) exceptions during     the switching of tasks. A local attacker could use this     flaw to terminate arbitrary processes on the system,     causing a denial of service, or, potentially, escalate     their privileges on the system. Note that this flaw only     affected systems using AMD CPUs on both 32-bit and     64-bit architectures. (CVE-2014-1438, Moderate)

  * It was found that certain protocol handlers in the Linux     kernel's networking implementation could set the     addr_len value without initializing the associated data     structure. A local, unprivileged user could use this     flaw to leak kernel stack memory to user space using the     recvmsg, recvfrom, and recvmmsg system calls.
    (CVE-2013-7263, CVE-2013-7265, Low)

  * An information leak flaw was found in the Linux kernel's     netfilter connection tracking IRC NAT helper     implementation that could allow a remote attacker to     disclose portions of kernel stack memory during IRC     DCC (Direct Client-to-Client) communication over NAT.
    (CVE-2014-1690, Low)

  * A denial of service flaw was discovered in the way the     Linux kernel's SELinux implementation handled files with     an empty SELinux security context. A local user who has     the CAP_MAC_ADMIN capability could use this flaw to     crash the system. (CVE-2014-1874, Low)

This update also fixes several bugs and adds multiple enhancements.
Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

Users are advised to upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.10.33-rt32.33, correct these issues, and fix the bugs and add the enhancements noted in the Red Hat Enterprise MRG 2 Technical Notes. The system must be rebooted for this update to take effect.

Multiple vulnerabilities has been found and corrected in the Linux kernel :

The compat_sys_recvmmsg function in net/compat.c in the Linux kernel before 3.13.2, when CONFIG_X86_X32 is enabled, allows local users to gain privileges via a recvmmsg system call with a crafted timeout pointer parameter (CVE-2014-0038).

The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8 on the AMD K7 and K8 platforms does not clear pending exceptions before proceeding to an EMMS instruction, which allows local users to cause a denial of service (task kill) or possibly gain privileges via a crafted application (CVE-2014-1438).

The yam_ioctl function in drivers/net/hamradio/yam.c in the Linux kernel before 3.12.8 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCYAMGCFG ioctl call (CVE-2014-1446).

The updated packages provides a solution for these security issues.

The 3.12.8 stable update contains a number of important fixes across the tree.
